STIRREB EEOR GAS-PRODUCERS.

Zb-all 'wlmmit may concern:

Be it known that I, J Anus A. HERRICK, a

"citizen of the United States of America, and

resident of Newark, in the county of Essex and State of New Jersey, (whose ost-oflice address is 90-West street, New Yor N. Y.,)

have invented certain new and useful. Im-

provements in Stirrers for Gas-Producers, of which the following is a specification.

This invention relates to gas producer ap j paratus, and has particular reference to the stirring means which may be employed to bring about the proper agitation of the mass within a producer.

One of the ob'ects of the invention to' provide in a producer apparatus a poker of novel and useful form, which is particu z,

larly ejfective, which is less liable to breakage than devices of the kind heretofore used, and Whose operative position relatively to provide a poker ofthe. kind referred to which is readily removable from the producer for substitution or repair.

Other objects and aims of the invention, more or less broad than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations, ar-

rangements of parts, and applications of principles constituting the'invention; and the scope of protection contemplated will appear'from the claims.

In the accompanying drawings, which are to be taken as a part of this specification, and in which I have shownmerely a pr ferred form of embodiment of my inventic Figure 1 is a sectional view, partly in elevation, showing my invention as applied to a form of gas producer; Fig. 2 is a detail in top plan; Fig. 3 is a detail in section; and Fig. 4 is another sectional detail.

Referring to the numerals on the drawindicates a section of a producer, which is adapted to be rotated in any usual manner not shown. The numeral 2 indicates the upper section of such producer, held against rotation in any suitable manner, and.

having a water-sealed connection with the section 1, as shown. The upper section 9. is provided with acover 3, which carries a fuel hopper 4: and arotating fuel distributing device 5. Since these parts do not enter into the invention they need not be further Specification of Letters Patent.

described. The cover portion 3 carries a poker to which this application is particularly directed. In Fig. 1, the cover portion is shown as provided with a plurality of openings, through which pokers such as shown in said fi ure and in Figs. 3 and 2 may be inserted into the interior of the producer. The poker shown at the left of Fig, 1 comprises a trunk 6 which depends from an annular portion 7 which is flanged as indicated at 8 to rest upon the portions of the cover surrounding the openings. 9 and 10 indicate prolongations of this trunk, said prolongations being preferably of different lengths and disposed at different angles to the of the trunk. The trunk and its prolongations' may be cast in 'onepiece as shown in Fig. A, or may be made in sections 'as indicated in Flg. 3. with ts prolongations s of such length that'it will extend well down into the lower section 1, so as to be in the most etiective position for stirring the fuel within theproducer. The trunkand the prolongations being hollow, as shown, water cooling of the poker is readily effected by means of a-supply pipe 11 entering through the upper end of the trunk and having branches 12 and 13 extending down into the several prolongations 9 and 10, a portion of the water flowing up around these branches and out from the top of the trunk, whence the water finds its way to the depressions 14in the cover and out through a drain pipe 15. The structure thus far described is useful in itself, the flanges 8 being bolted to the cover, with the legs 9 and 10 extending down into the fuel,

so that upon rotation of the lower section 1 the poker will serve to agitate the mass. If desired, however, the poker may also be made revolublc. This may be accomplished, as shown in Fig. 1, by providing the trunk (3 with an integral or rigidly attached tubular extension 16 at its upper end which will project above the cover 3 when the poker is in place, to which extension 16 may be secured a gear 17 which may be riven as by means of meshing gears 18 and 19, operated as by means of a crank 20. By these means it is obvious that the poker may be turned as desired within the producer, the flanges 8 being of course not bolted to the cover if the poker is to be revolved. Furthermore,-

Preferably the poker by removing the gear 1'? and replacing it e of the structure shown at the right of Fig.

1 and in Fig. 3.- As there shown, the trunk 6 is externally threaded and projects above the cover 3. Cooperating with the threaded end of the trunk is a nut 21, with respect indicated at 22, and the supporting member- 7 being preferably separate from the trunk G and having threaded engagement therewith as shown. By this means, if the wall of the producer should become incrusted, the poker may be moved up and down, so that its field of operation will include the portions of the wall which it is desired to clean, and the lateral approach of the oker to the side wall of the casin 1 may e regulated either by changing the gear 17 so that the oker will be bodily moved with respect to the wall of section 1, or by rotating the poker from handle 20 so that that one of the prolongations l().will be nearest the wall of section 1 whose angular relation is such that it will approach said wall more closely. Nhere the poker is to be rotated, as at the left of Fig. 1, and Where it is contemplated that various sized gears may be used in place of gear 17, and where consequently the shouldered part 23 of the poker is of smaller diameter than the opening in the cover, it is obvious that some means would need to be provided for keeping the gear 17 strengthening web 24. Although it is pre-' ferred to mount the poker in the cover of the producer, it is quite evident that it might beelsewhere supported, for instance, in the side wall, or upon the twyer box, 111 which event of course some slight alterations would need to be made in order to adapt the poker to its newlocation.

limiting sens-e.

As many changes could be made in the above construction, and many apparently widely different embodimentsof my invention could be made without departing from the scope thereof, it is intended that all mat ter contained in theabove description or shown in the accompanying drawings shall be interpreted as illustrative and not in a it is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein,

described and all statements of the scope of.

the invention which, as a matter of language, might be said tofall therebetween.

I claiml. A gas producer having a cover portion, and a stirring member depending from the cover portion into theproduoer, said stirring member being bodily shiftable laterally. Y

.2. A gas producer having a cover portion, and a stirring member depending from the cover into the producer and bodily movable vertically and horizontally with respect to the producer. v

3. A gas producer havin an opening in its cover portion, and a bi urcated stirring member adapted to be inserted through said openin and having a flanged part to rest upon t e cover portion about-the opening, said opening in the cover portionbeing of a size-to permit of the ,bodily withdrawal therethrough of the bifurcated stirring member. I

4. A gas producer having an opening in its cover portion, a stirring member bifurcated at one end and having a flanged part intermediate its ends adapted to rest upon the cover portion about the opening, and poker-actuating means detachably connected to the other end of the stirring member.

5. A gas producer having an opening inv its cover and a stirring member of such a size that it is insertible and withdrawable through said opening, said stirring member being bifurcated at one end and having intermediate its ends a horizontal flange adapted to rest upon the cover about said Copies of this patent may be obtained for in cents each, by aderesslng the Commissioner of Patent:
